its B, not A....
consider number 3, add 3 to 3 three times. i.e 3 + '3 + 3 + 3' = 12 i.e even number.

the answer is absolutely odd no.bcoz eg 3+3+3+=3(3)=9 not 12.
3(5)=15.

@guttam

it must be and even number, the question is to add an odd number to itself odd number of times not to multiply

if the number is 3, and we all know 1 is an odd number adding 3 one time to 3 yields, 3+3= 6 or 3+(3+3+3) = 12 and so on ...

so the answer definatley is

B and even nnumber
